Tri-Cortex Engine

The Tri-Cortex is MindFry’s decision-making brain, implementing Balanced Ternary Logic inspired by the Soviet Setun computer.

Balanced Ternary Logic

Unlike binary (0, 1), balanced ternary uses three values:

Trit	Value	Meaning
`True`	+1	Excitation / Yes
`Unknown`	0	Neutral / Maybe
`False`	-1	Inhibition / No

The Octet (Personality)

MindFry’s personality is an 8-dimensional vector of Trits:

pub struct Octet([Trit; 8]);

pub mod dimension {
    pub const OPENNESS: usize = 0;
    pub const CURIOSITY: usize = 1;
    pub const PRESERVATION: usize = 2;
    pub const AGGRESSION: usize = 3;
    pub const SOCIABILITY: usize = 4;
    pub const CAUTION: usize = 5;
    pub const CREATIVITY: usize = 6;
    pub const EMPATHY: usize = 7;
}

Mood & Consciousness Threshold

The Cortex maintains a mood value from 0 to 1:

τ(μ) = 0.5 × (1 - μ)

where μ = mood ∈ [0, 1]

Mood	Threshold	Accessibility
1.0 (Euphoric)	0.0	All accessible
0.5 (Neutral)	0.25	Medium-energy+
0.0 (Depressive)	0.5	High-energy only

Resonance Filtering

Data can have its own Octet. Resonance measures compatibility:

resonance(P, D) = (1/8) × Σᵢ (Pᵢ × Dᵢ + 1) / 2

High resonance = data feels “natural” to this personality.

Quantizer

The Quantizer converts continuous signals to discrete Trits:

impl Quantizer {
    pub fn quantize(value: f32) -> Trit {
        if value > 0.33 { Trit::True }
        else if value < -0.33 { Trit::False }
        else { Trit::Unknown }
    }
}
